1988年7月～12月我科采用CO_2激光治疗色素痣、疣等各类皮表肿物共150例,收到比较满意疗效。 1 资料和方法 我们采用长春医疗光电仪器厂制造的JZ—25型CO_2激光治疗机。波长10.6μm,输出功率25W,消耗功率400W,冷却水温35℃,调节电压至100～125V,光斑0.5～1.0mm。照射距离病灶1.0～2.0cm。病人取仰卧或坐位,局部常规消毒,用1％盐酸利多卡因局部浸润麻醉之后,用CO_2激光点射或连续烧灼病变区,根据病灶超出皮肤高度决定碳化或气化。治疗结束时,均以放大镜检查有无残留病变组织,如有时则清除焦痂后再行烧灼,并保护创面。若病灶面积大有渗出时,给予小剂量紫外线照射,并暴露创面即可。
July 1988 ~ December Department of CO_2 laser treatment of nevus, warts and other types of skin surface tumor a total of 150 cases, received more satisfactory results. 1 Materials and Methods We use JZ-25 CO_2 laser treatment machine manufactured by Changchun Medical Optoelectronic Instrument Factory. Wavelength 10.6μm, output power 25W, power consumption 400W, cooling water temperature 35 ℃, adjust the voltage to 100 ~ 125V, spot 0.5 ~ 1.0mm. Irradiation distance lesion 1.0 ~ 2.0cm. Patient supine or sitting, local routine disinfection, with 1% lidocaine local anesthesia after anesthesia, CO 2 laser spotting or continuous burning of the lesion, depending on the lesions beyond the skin height to determine carbonation or gasification. At the end of the treatment, both with a magnifying glass to check for residual disease tissue, and sometimes remove the eschar escalation cauterization and protection of the wound. If the lesion area is large oozing, given a small dose of ultraviolet radiation, and exposure to the wound can be.
